Re: Asking CVS if a repository/module/tag exists.

[Arcin Bozkurt - Archie]

you can use the -n option to cvs...
copying from man cvs:

-n     Do  not  change  any files.  Attempt to execute the
             cvs_command, but only  to  issue  reports;  do  not
             remove,  update,  or  merge  any existing files, or
             create any new files.

      -t     Trace program execution; display  messages  showing
             the  steps  of  cvs  activity.  Particularly useful
             with -n to explore the potential impact of an unfa­
             miliar command.
